Customize the UIPickerView bar Swift

Question

I'm wanting to change the appearance of the bar on the picker view, and I have no idea where I would go about doing this? I would like to make it look like it does in the image.

Thank you in advance, all help is appreciated

1. Hardcode your background to something like:
   

2. Set your font when selected value changes

   func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
       for index in 0 ..< self.pickerView(pickerView, numberOfRowsInComponent: component) {
           if index != row {
               // reset to unselected font for this index here
               // ...
           } else {
               // apply the selected font for this index here
               // ...
           }
       }
   }
   

For customizing the font, you may need to use pickerView(UIPickerView, viewForRow: Int, forComponent: Int, reusing: UIView?) as noted by Kamran.
